To my knowledge, almost every faction (official or not) has some sort of out-of-game comms. Typically skype acting as both a faction chat room and a batphone to summon backup, as well as voice chat for big fights. In the sense that I'm used to, this is directly metagaming - saying "There's two smugglers in New York. Someone log on a Lawful and help me grab the other one" is questionable at best.
Where is the line? What is okay? What is not okay?
